  • Publication number: 20070074522
    Abstract: A cryogenic refrigerator has a separating device provided between a lower temperature portion and a heat exchanger to selectively separate the lower temperature portion and the heat exchanger, and thus to selectively block heat transfer between the lower temperature portion and the heat exchanger. According to the cryogenic refrigerator, it can have an ability to perform a maintenance operation of the cryogenic refrigerator at normal temperature by blocking heat transfer from the lower temperature portion to the heat exchanger during maintenance after disassembly.

  • Patent number: 6983609
    Abstract: A heat driven acoustic type pulse tube cryocooler has metal knit installed within a driving section cooling a driving gas of an application device using a principle of high temperature superconductivity, and then homogeneously heats the driving gas by way of premixed combustion so that the driving gas generates an acoustic having a predetermined frequency. The orifice installed within a reservoir controls the amount of the driving gas running between the cold reservoir and the pulse tube to constantly maintain a pressure of the cold reservoir. Therefore, the driving gas repeats the process of the compression and expansion centering around the pulse tube, thereby cooling the application device.

  • Patent number: 6817210
    Abstract: The present invention relates an absorptive high temperature desorber for mechanically narrowing the width of the combustion area, and an absorption chiller-heater using the absorptive high temperature desorber. The high temperature desorber comprises a plurality of combustion chambers, a group of liquid ducts arranged in the perpendicular direction in the combustion chambers, and the distribution chambers independently supplying a mixing gas to the plurality of combustion chambers. Therefore, the high temperature desorber can form flame independently and variably in the combustion chamber, and has a mechanically small width.
